This example visualizes a world map using D3.js with a blue sphere background and green country shapes. It loads geographic data from an external JSON file and renders it as SVG paths using the `d3.geoPath` and `d3.geoNaturalEarth1` projection. The code employs TopoJSON’s `feature` method (though not yet called in the visible portion) and logs the fetched data to the console. The styles define the sphere’s fill color and country borders with a low stroke opacity.
